GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent N o. 674,772,6.ated May 21, 1901. Application filed October 20, 190. Serial No. 33,726. (No model.)

T0 a/ZZ whom, t may concern:

Be it known that I, HARRY HYATT, acitizen of the United States, and a resident of Cleveland, Ohio, have invented certain Improve ments in Gas-Producers, of which the following is a specification.

The object of my invention is to effect a thorough agitation of all parts of the mass of incandescent fuel ina gas-producer, so as to prevent the formation of clinkers, insure the proper descent of the fuel in the producer, and provide for a free and uniform flow of air through the mass of fuel. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of a gas-producerwith poker mechanism in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged View of the poker and its bearing, and Fig. 4 is a plan view illustrating a modification of my invention.

So far as concerns the producer proper it is immaterial how the same is constructed, my invention having no reference to the particular construction of the producer, but being devoted wholly to the means employed for agitating the mass of fuel therein.

The producer shown in the drawings consists of a cylindrical sheet-metal shell 1 with fire-brick lining 2, mounted upon posts or columns 3 and having a depending tapering ash-hopper 4, which extends into a sealingpit 5, air to support combustion being supplied through a central air-distributer 6 and the producer having a suitable cover 7, with fuel-feed hoppers 8 thereon. The poker 9, whereby the agitation of the fuel is effected, consists of a tube closed at both ends and having a spherical enlargement 10, adapted to a central bearing on the top of the producer, so as to form a ball-and-socket joint, which permits of a universal swing of the poker. lVithin the poker and extending down close to the lower end of the same is a pipe 11, and both the pipe and poker have at points above the top 7 of the producer branches communicating, respectively, with water supply and discharge pipes 12 and 13, so that water may be conveyed to a point close to the inner end of the poker and then permitted to flow upwardly through the poker,

so as t0 properly cool the latter and prevent rapid destruction of the same by the heat to which it is subjected.

Suitably mounted above the top of the producer by means of posts 15 is a fixed annular rack 16, with which engages a spur-wheel 17, said spur-wheel also engaging with a pin- 6c ion 18, occupying a position at the center of the annular rack 16 and carried by a vertical shaft 19,to which rotating movement may be imparted in any suitable manner. The spur-wheel 17 is supported in any desired 65 manner-as, for instance, by resting upon flanges on the rack 16 and pinion 18-and said spur-wheel has an opening with beveled walls for the reception v of the projecting end of the poker 9, whereby said upper end 7o of the poker partakes of any movementwhich may be imparted to the spur-wheel. As shown in the drawings, this is what is known as a sun-and-planet movement-that is to say, the spur-wheel is caused to rotate about its own axis, while at the same time it has imparted to it movement of rotation about the axis of the pinion 18, and as the lower end of the poker,which projects into the mass of fuel, reproduces in exaggerated form the 8o movements imparted to the upper end of the poker by the spur-wheel 17 it follows that said lower end of the poker will be carried around through the mass of fuel in the producer and while being thus carried around will have movement from and toward the center of the producer, the result of this joint movement being the thorough agitation of all parts of the mass of fuel, with the resultant breaking up of clinkers and the insure 9o ing of a proper, free, and uniform flow of air through the mass.

While I prefer to employ the mechanism described for imparting movement to the poker,other means within the scope of my invention may be used for the purposeforinstance, in Fig. 4 l have shown two vertical shafts 24 and 25 disposed at ninety degrees in respect to each other, one having a crank 26 and the other a crank 27, each of these Ioo cranks being connected by a rod 28 to the outer end of the poker 9, ball-and-socket or other universal joint connections between the rods and the poker and crank-pins providing for the variety of angles assumed by the rods. It will be observed that inboth cases where the means for imparting vibration tothe poker have different aXes of rotation every point on the poker within the producer will describe a curve resembling or substantially approximating a hypocycloid-that is to say, a curve traced by a point upon the circumference or within the circumference of a small circle rolling internally upon a larger circle.

By suitable timing of the cranks 26 and 27 an irregular gyratory motion may be imparted to the poker 9, so that every portion of the mass of incandescent fuel within the producer will be periodically acted upon by the poker and the desired thorough agitation of the mass thereby insured.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination of a gas-producer,with a poker universally mounted thereon, and means having different axes of rotation for' imparting irregular movement of rotation to stantially as specified.

3. The combination of agas-producer, with a poker universally mounted thereon, and a sun-andfplanet gear engaging the projecting portion of said poker and imparting movement thereto, substantially as specied.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HARRY HYATT.
